Negative sign (–)
Note:
When squaring a negative value (such as –2), the value
being squared must be enclosed in parentheses (
2
7;
). Since
x
2
has a higher priority than the negative sign,
inputting
2
7
would result in the squaring of 2 and then
appending a negative sign to the result. Always keep the priority
sequence in mind, and enclose negative values in parentheses
when required.

Important:
• Certain types of expressions can cause the height of a
calculation formula to be greater than one display line. The maximum
allowable height of a calculation formula is two display screens (31 dots
s
2).
Further input will become impossible if the height of the calculation you are
inputting exceeds the allowable limit.
• Nesting of functions and parentheses
is allowed. Further input will become impossible if you nest too many functions
and/or parentheses. If this happens, divide the calculation into multiple parts
and calculate each part separately.
Note:
When you press
and obtain a calculation result using Natural
Display, part of the expression you input may be cut off. If you need to view
the entire input expression again, press
and then use
B
and
C
to
scroll the input expression.
Using Values and Expressions as Arguments
(Natural Display only)
A value or an expression that you have already input can be used as the
argument of a function. After you have input
7

, for example, you can make
it the argument of
